Opensolr MCP Overview

opensolr-mcp MCP server exposes managed Apache Solr capabilities to AI agents through tools for hybrid BM25 plus kNN search, semantic retrieval, indexing, and grounded RAG answers. Opensolr handles embeddings and derived document fields server-side, while writes use an asynchronous ingestion pipeline. It also supports image-based queries that extract visual labels, OCR text, and barcode or QR data without storing an image vector. Reach for it when an agent needs hosted Solr retrieval and document management without operating a separate embedding model or vector database.
